Ellies Satellite dish: Rusty bracket causes failure

I have one of Ellies Satellite dishes which I have had for many years. The dish is fine, yet the bracket attaching to the dish is completely rusted and falling apart. The only way to remedy the situation is to buy a completely new Satellite dish with bracket as clearly they are forcing consumers to buy a complete unit, when all that needs replacing is the bracket despite the fact the dish is fine. I am not even living in a coastal location! They don't supply a replacement bracket alone and cant even bother to have the bracket anodised from their Chinese suppliers.
